Method for collecting teaching process in real time by mobile devices

Abstract

The invention discloses a method for collecting a teaching process in real time by mobile devices. The method comprises the following steps of shooting the teaching process with two or more mobile shooting device, wherein the two or more mobile shooting devices comprise a reference shooting device; establishing a reference coordinate system by taking the left lower corner of the image shot by thereference shooting device as an original point; performing coordinate transformation on the images shot by other mobile shooting devices to the reference coordinate system; carrying out the radial distortion adjustment on the image subjected to the transformation coordinates; and capturing the feature points of the image after distortion adjustment, and splicing the images to enable the same feature points in the images shot by the different mobile shooting devices to be superposed. According to the method, the mobile device are used for collecting the teaching process in real time, the mobiledevices do not need to be debugged even if the environment of the classroom is different, and the captured images are processed through the steps, so that the recording of the whole teaching processis realized without missing the starting part.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for real-time acquisition of a teaching process by using a mobile device. Background technique [0002] Teaching video class is to record the entire classroom teaching process through video cameras and other video equipment, objectively record the teacher's teaching process, the student's learning process and the teaching scene of teacher-student interaction, and truly reflect the audio and video digital files of the classroom teaching effect. Because the teaching video course can objectively reflect the whole process of classroom teaching, including the teacher's teaching philosophy, teaching ability, teaching content, teaching resources used, teacher's organization of the teaching process, bilateral interaction between teachers and students, and the resulting teaching experience. Therefore, it is playing an increasingly important role in promoting excellent classroom...
